+Toppoly TD028TTEC1 Panel
+========================
+
+Required properties:
+- compatible: "toppoly,td028ttec1"
+
+Optional properties:
+- label: a symbolic name for the panel
+
+Required nodes:
+- Video port for DPI input
+
+Example
+-------
+
+lcd-panel: td028ttec1@0 {
+       compatible = "toppoly,td028ttec1";
+       reg = <0>;
+       spi-max-frequency = <100000>;
+       spi-cpol;
+       spi-cpha;
+
+       label = "lcd";
+       port {
+               lcd_in: endpoint {
+                       remote-endpoint = <&dpi_out>;
+               };
